With Arctic air firmly entrenched over the Prairies, the weather will be relatively quiet and cold for Winnipeg.

The forecast for this week will be a pretty straightforward one; little change is expected across the region through the work week. Arctic air will remain in place over the area, bringing cool daytime highs generally near -20 °C — perhaps a degree or two warmer at times — and overnight lows dipping down into the low -20s or the -30s. Wind chill values of -30 to -40 will be common through the week, with the change that some nights will bring wind chill values of -45 to -40, which would qualify for extreme cold warnings from the Meteorological Service of Canada.

The wind will be light out of the south at 10 to 20 km/h today, then shift to light and variable on Wednesday as a weak trough of low pressure moves through the region. It will exit later Wednesday and bring light northwest winds back to the area. Winds will then shift to the south and pick up into the 10 to 20 km/h range on Thursday as a surface high passes to the south and a weak low pushes towards western Manitoba.

Little weather will impact the region this week. The Winnipeg area will see sunny skies today, followed by some cloud cover on Wednesday as the trough moves through. Skies should clear up Wednesday night bringing sunshine back to the region for much of Thursday. Some cloud may begin to push in late in the day as that low pressure system nudges into the province.

When there is cloud cover, there’s a chance that the region could see some light snow or ice crystals; no notable accumulating snow is expected this week though.

Long Range Outlook

Heading into the weekend, another Arctic high will gradually shift across the Prairies. This will bring northwest to westerly winds with clearing skies. Temperatures will stay cold with similar temperatures through the weekend as seen during the week.

So it’s cold and quiet weather ahead. Fortunately it’s not as intense a deep-freeze as sometimes…I’ll take highs near -20 °C over those ruthless cold snaps where we barely reach -27 °C. That said, the nights will be cold and there will be little relief likely until the last week of February. Stay warm!

Today’s seasonal daytime high in Winnipeg is -9 °C while the seasonal overnight low is -19 °C.

Skies will gradually clear this weekend in Winnipeg as the Polar Vortex slumps towards the region.

A weak disturbance dropping through the region will bring mixed skies to the Winnipeg area today. Temperatures will be similar to yesterday with a high in the -10 to -15 °C range, but winds will be much lighter at only around 15 to 20 km/h.

Skies will clear out a bit tonight, but a disturbance moving through the United States will spread a bit more cloud into southern Manitoba overnight into Saturday. Temperatures will dip down into the -25 to -20 °C range overnight with light winds.

On Saturday, Winnipeg will again see mixed skies with some morning cloud breaking up into the afternoon. Temperatures will be cooler with highs dipping to the -20 to -15 °C range with light winds.

By Saturday evening, the next big pattern shift for the region will be underway. An axis of colder air will begin building into the Prairies as the Polar Vortex begins to slowly drop southwards through the Arctic. This will entrench this first temperature drop into the region through the rest of the weekend.

Lows will dip into the -30 to 25 °C range on Saturday night with mainly clear skies and light winds.

On Sunday, a weak disturbance slumping through along the leading edge of colder air will slide through the region. It will bring mixed to cloudy skies with a chance of flurries to the region. For the Winnipeg area, a bit of snow will be most likely in the afternoon, while it will be earlier to the north and west. Daytime highs will climb back into the -20 to -15 °C range.

Some clouds will linger on Sunday night ad temperatures dip into the mid-minus 20s.

Long Range Outlook

Next week will be dominated by a single weather feature: the Polar Vortex. It will continue to drop southwards and build into the Prairies, bringing cold weather to the entire region.

Daytime highs will drop below -20 °C early next week with lows dipping close to -30 °C. There will be little change in the following 10 days. Daytime highs will largely sit in the -20s, save for the occasional passing disturbance that brings highs into the low minus teens. Overnight lows will dip into the low -20s or -30s many times right into mid-February.

It will be a prolonged stretch of cold weather that shows little sign of breaking down until late in the month. Extreme cold warnings will likely be issued by the weather office at times next week for the region.

We hope you all have a great weekend and we’ll see you back here in the deep freeze next week!

Today’s seasonal daytime high in Winnipeg is -10 °C while the seasonal overnight low is -20 °C.
